8. The device of claim 1 , wherein the at least one processor is further configured to: generate a plurality of pieces of thumbnail information corresponding to the plurality of objects, match up the plurality of pieces of thumbnail information to additional information of the plurality of objects, and store the matched thumbnail information and additional information in a memory.
9. The device of claim 1 , wherein the display is further configured to: display the handwritten content in a first area of a screen, and display a list of thumbnail information corresponding to the respective plurality of objects in a second area of the screen.
10. The device of claim 1 , further comprising a user interface configured to receive a third input to select a plurality of pieces of handwritten content, wherein the display is further configured to display a list of thumbnail information corresponding to objects included in the plurality of pieces of handwritten content.
11. The device of claim 10 , wherein the user interface is further configured to receive a fourth input to select first thumbnail information from the list, and wherein the display is further configured to display additional information of a first object corresponding to the first thumbnail information.
12. The device of claim 10 , wherein the user interface is further configured to receive a fourth input for selecting first thumbnail information from the list, and wherein the at least one processor is further configured to: retrieve a first piece of handwritten content including a first object corresponding to the selected first thumbnail information from among the plurality of pieces of handwritten content, and control the display to display the retrieved first piece of handwritten content.
13. The device of claim 10 , wherein the user interface is further configured to receive a retrieval condition, and wherein the at least one processor is further configured to: retrieve at least one object satisfying the retrieval condition, and control the display to display a list of thumbnail information corresponding to the at least one retrieved object.
14. The device of claim 1 , wherein the at least one processor is further configured to: determine access rights information for the respective plurality of objects included in the handwritten content, and control the display to display some of the plurality of objects based on the access rights information.
15. A method of providing handwritten content in a device, the method comprising: displaying handwritten content on a screen; displaying a scroll bar with a moving element indicating a segmentation level, the scroll bar being displayed to overlap the handwritten content based on a first input received on the displayed handwritten content, wherein the segmentation level indicates units for segmenting the handwritten content; identifying the segmentation level of the handwritten content based on an adjustment associated with the moving element of the scroll bar; segmenting the displayed handwritten content into a plurality of objects by grouping strokes included in the handwritten content based on the identified segmentation level; processing each of the plurality of objects into selectable objects; identifying one object type of a plurality of object types corresponding to each of the selectable objects of the handwritten content based on a pattern of the strokes included in each of the selectable objects of the handwritten content; displaying a list of the selectable objects, on the screen; and displaying labels respectively indicating the identified object type corresponding to each of the selectable objects of the handwritten content wherein each of the selectable objects is part of the handwritten content and each of the identified object type is one of the plurality of object types of the handwritten content.
16. The method of claim 15 , further comprising: receiving the first input to select at least one object from among the plurality of objects; and displaying an image for identifying the at least one selected object on the handwritten content.
17. The method of claim 15 , further comprising: receiving the first input to select at least one object from among the plurality of objects for a set time or longer; and switching an operation mode to an edit mode for editing the at least one object based on the first input.
18. The method of claim 17 , wherein the switching of the operation mode to the edit mode comprises: receiving a second input for moving a first object from among the plurality of objects; determining whether a second object from among the plurality of objects and the moved first object overlap; and displacing the second object a certain distance apart from the first object when the second object and the moved first object overlap.
19. The method of claim 15 , further comprising: receiving a new handwritten input on the handwritten content; determining whether an input area in which the new handwritten input is received and the plurality of objects included in the handwritten content overlap; and displacing at least one object overlapping the input area a certain distance apart from the input area based on a result of the determining.
20. The method of claim 15 , wherein the displaying of the handwritten content comprises changing an arrangement of the plurality of objects included in the handwritten content based on a certain template.
